没区别啊,U TURN后面有车就要放弃U TURN的,这个是路考常识
三点掉头也一样啊,后面没车才可以做,总之 ...
Three-point turns are used when a road is not wide enough to do a
U-turn.
However, because it takes longer to do a three-point turn, in heavy traffic or on
busy roads it is often safer to turn around by driving around the block instead.
Before commencing a three-point or U-turn, signal, check mirrors and blind spots.
After completing the turn, signal and check mirrors and blind spots, before
rejoining the traffic. |
